I only have four, two at 4 5/8" and two at 4 1/8" that were longer barrels. All are blued.
#1. is a Vaquerito with it's original, steel short grip frame and steel ERH, case colored frame.
#2. is an original but with stainless steel XR3-RED grip frame, blue steel ERH.
#3 is 4 1/8" (was 5 1/2"), steel XR3 grip frame and steel ERH from a new model flat top. I reamed the cyl chambers to 32-20 (also still chambers 32 H&R Mag). The 32-20 ammo has to have the bullet seated deeper than normal. The loading chute is enlarged slightly for the larger .32/20 case rims.
#4 is 4 1/8", with Vaquerito short steel grip frame and I deepened the Cyl chambers 1/8" and it also chambers 327 Fed Mag*.
*It is true that all the 'professional' 327 conversions use a longer new made cylinder that fills the cyl window with no barrel protruding thru the frame. But after speaking with a few custom builders, they had no concerns about the 32 H&R Mag cyl strength when reamed 1/8” deeper for the 327.
I do not build cylinders and did not like the price of custom built cyls. I decided the factory .32 Mag cyl would have to do. Factory loaded .327 Mag cartridges are only ~.003” longer than the factory 32 H&R chambers. Originally I thought I'd have to run the factory loads thru my seating die and seat the bullets a couple of .001" deeper in the case, but didn't have to. Believe it or not they function perfectly by taking advantage of the barrel/cylinder gap spacing. I know it might be counterintuitive but as they say, truth can be stranger than fiction. Even though the .327 Fed mags in the 85 Gr HP Hyrda shock and 100 gr FP loads are longer than the .32 H&R Mag chambers, the ~ .005" bar/cyl gap is sufficient for the loaded cyl to rotate w/o interference.
The 32 H&R Mag is carried by many for self defense, reportedly equal to 38 Spl + Ps. Hand loading can really improve the 32 H&R potential but then some worry about carry gun liability with hand loaded ammo. Therefore I prefer the .327 factory ammo for a carry gun.
My #2 Super Single Six Magnum .32 H&R Mag Bisley hammer with modified spur, Stainless Steel grip frame, steel ejector rod housing, SBH grooved trigger w/web removed, Colt ejector rod, and free-spin cylinder pawl for ease of aligning the chambers with the loading gate.
